Referring by numerals to the accompanying drawings, it indicates a framework comprising a base structure El, and an upper structure l2. The lower structure consists of a pair of side frames M connected together at their front ends by a member i5 and at their rear ends by a transversely disposed top member I I6 and an angle iron l'l arranged near the lower ends thereof. s

The upperstructure consists of afront end member l8 and a rear end member l9 connected together at their upper ends by a pair of tie rods 26 and a top member 2!, while the lower ends of said members [8 and I9 are secured to the base structure It].

Each side frame 14 consists of a single piece casting having a front member l5 and a rear leg 23 connected together at their upper ends by a rail 24 and near their lower ends by a rail 25. An intermediate vertically disposed member 26 extends between rails 24 and substantially equidistant from the legs 22 and 23.

The canvas strips are supplied in rolls and two rolls are generally used as indicated at A and B. Thus two canvas strips C and D of varying widths can be used with inner soles of small and large sizes. These rolls are supported in the lower structure H by carriers 21 and 28 which are identical in size and construction but are disposed on different levels, carrier 21! supplied with roll only A being disposed above carrier 28 carrying roller B.

Each carrier is open on top and has a horizontally disposed bottom 29 and a vertically disposed rear wall 30 and one side wall 3!. The outer side of each carrier is open and extending horizontally across said side is a bar 32. This bar is pivotally' mounted at one end to the end wall 3] and has its forward end adapted to rest in a U-shapedmember 33 fixed to the forward end ofthe carrier. This forward end is preferably inclined upwardly and forwardly, as indicated at 3 1, and terminates in a horizontally disposed portion 34a. Carrier 21 is supported at its rear end by a rod 35 fixed to and extending horizontally between intermediate frame members 26 and at its forward end by a pair of lugs 36 formed integral with the rear wall of frontend rne1nberl5, "the horizontal portions-34a. of carrier 2'l-r'esting o'n-said lugs. a 1

Carrier 28 is supported at its rear end by a rod 3'! fixed to and extending between rear legs 23 and at its forward end on a rod 38 fixed to and extending between the intermediate frame members 26 a suitable distance below rod 35. A roller 39 is journaled in each carrier adjacent to the bottom and rear end thereof and the axis of each roller is disposed parallel with the axis of the roll of canvas arranged in said carrier. The purpose of rollers 33 is to form stops for the rolls and facilitate the movement of said strips. their front sides to facilitate the positioning of rolls of canvass therein. The bars 32 serve to hold the rolls in place in the respective carriers.

The canvas strips C and D extend rearwardly from their respective rolls A and B to a slack producing mechanism 4i! mounted in the rear of base structure it, and thence upwardly over rollers 4i and A2 journaled in the rear member 43 of the top member 21. This top member 2| is slidably mounted for movement transversely of the machine. It consists of a fiat table or plate Zia, the rear end of which is secured to said rear: end member 43 while the front end is secured to the front end member 43. Member 43 is provided with a downwardly presented tranversely disposed seat 430 which slidably rests upon the horizontally and transversely disposed flange of the upper end lea of rear member is.

Member 53 is formed with rearward extensions 33!) in which are journaled side rollers M and 42 and with upward extensions 430 in which are pivotally mounted horizontally and transversely disposed retainers 45. These retainers extend obliquely and forwardly and are'provided at their lower edges with teeth which rest upon the canvas strip and prevent rearward movement thereof, without interferring with the forward movement.

The front end member 56 is provided with a downwardly presented seat Ma which slidably rests upon the horizontally and transversely disposed flange of the upper end l8a of the front member l8. This front end member M is provided at each end with a forward extension Mb in which are journaled roilers 46 over which the canvas strips pass downwardly. Pivotally mounted on said extensions 44b is the upper end of a vertically disposed guide or track member 41 over which the strips are passed downwardly. This guide is spaced forwardly of the front member l8 and is provided at each side with a longitudinally disposed flange lla which serves to confine the strips in proper positions. to hold the lower end of said guide yieldably in an extended position, as shown in Figures 9 and 10. As stated before there are two rolls A and B of canvas strips provided. These strips are of different widths, strip D of roll B being of greater width than strip C of roll A. The purpose of providing two strips of different widths is to permit the use of the narrow strip with small size inner soles and of the wide strip with large sized inner soles. The two strips are disposed side by side and are always ready for use. Either strip can be placed in operating position by the shifting of carriage or top member 2i and its end members 33 and M on the upper ends liia and la of the frame. As shown in the drawings, the carriage 2! is so located that the narrow strip C is in operating position while the wide strip D is to one side of the operating line.

The lower end of this guide terminates above and to one side of a suitable severing mechanism 49 which is disposed on the outer side of member The carriers 21 and 28 are left open on,

A spring 48 serves' I5 adjacent to a table or shelf 50. The latter is mounted on member l5 and extends forwardly therefrom substantially on a horizontal plane with an elongated horizontally disposed opening 5| formed in member 15. The severing mechanism 59 is in the instant case in the form of a shears presented with their open ends toward the operating side of the machine, as shown in Figure 11.

The stationary or lower blade 49a of the shears is disposed slightly above the horizontal plane of said table 58 and said opening 5|. The guide 4'! is held yieldably by spring 48 in an extended or outward position as shown in Figures 10, 15 and 16 but is moved inwardly into the position shown in Figure 1'7 just before the severing mechanism 49 is set in operation, as hereinafter more fully described.

Member I5 is preferably in the form of a vertically disposed narrow box having an exhaust chamber 15a. The front of this box is closed by a door I51) and the table 50 and said severing mechanism 39 are preferably mounted on said door. A packing 52 is arranged between said door I51) and the door opening in member I5 in order to provide a substantially air-tight joint when the door is closed.

Table 55 is formed adjacent to its point of securement to said door I5b with a stepped portion 580. so as to provide the necessary clearance for blade 49a and a guard plate 53, which latter is secured to said stepped portion 500. in spacedapart relation with the severing mechanism 59 and extends upwardly a suitable distance above table 58. A horizontally disposed opening 53a is formed in said guard plate through which the free end of the canvas strip is threaded and through which the inner sole is passed outwardly. This guard plate prevents the hand of the operator from coming in contact with the severing means 59 and protects it against injury.

Formed in the upper end of lower structure II is a box-shaped compartment 54, the bottom wall of which is formed by a horizontally disposed plate 55 secured to inwardly extending flanges 24a of side rails 24, while the latter form the side walls of said compartment 54. Member Hi forms the rear wall and member l5 the front wall of said compartment 54. A cover 56 is hinged to one of the rails l4 and forms the top wall for the intermediate portion of compartment 54. The rear portion of this compartment is closed permanently by a plate 5'7. A' partition wall 58 extends longitudinally in compartment 54 and is co-extensive with cover 55. Thus the compartment 54 is divided into two longitudinal chambers 54a and 541) which communicate with each other at their rear ends and are separated from each other at their front ends. by a wall 59 which extends between member [5 and the corresponding end of partition wall 58.

The forward end 54d of chamber 540. is open on top and receives the inner sole to be sprayed. The bottom wall 55a of this open end slopes downwardly and rearwardly toward the covered portion of chamber 54a and at a point of juncture with the horizontal bottom wall 55 a plate 68 of comparatively short height is secured transversely of the chamber. This plate serves to arrest the surplus spray material which may collect on said bottom. A drain opening 60a is formed in said bottom wall 55a adjacent to said plate and allows the liquid collected therein to drain into a receptacle 5i supported in said base structure I l below said drain opening.

The chamberlifia is provided with a plurality of spaced-apart baflie plates 62. These plates are removable for cleaning purposes and preferably they are attached to partition wall 58 which is also removable. The air and spent sprayed material are drawn into chamber 54a and in passing therethrough the latex carried by the air is deposited on said bafile plates. The air then passes from chamber 54a to chamber 54?) and passes forwardly therethrough and enters chamber |5a through an opening 540. A cover 53 closes the front end of chamber 542).

The lower end of chamber l5a is provided with an opening 64 in which operates an exhaust fan or blower 65 enclosed by a housing 66. An air discharge 6'! leads from said housing and opens to the atmosphere. Blower 65 is operated by an electric motor 68 mounted in the base structure ll.

Thus the air is drawn from the spraying chamber 54d through chambers 54a and 54b, thence through opening 540 into exhaust chamber l5a From this chamber it is then exhausted by the blower 65 and discharged to the atmosphere through the discharge conduit 51.

The latex particles contained in the air are deposited on the bafile plates 62 and on the walls of the respective chambers 54d and 542) so that the air upon reaching the blower and the discharge conduit 61 is practically free of all latex. As the bafile plates 82 and partition wall 58 are removable, they can be readily cleaned at regular intervals of the accumulated latex deposited thereon. Chambers 54a. and 54b can be cleaned by moving the cover 56 into open position. This cover which forms the top or table of the base structure H can be used to hold a number of inner soles in readiness for spraying operation, as indicated in dotted lines in Figures 1 and 3. The rear edge of this cover is provided with a longitudinally disposed upwardly projecting flange 56a which serves to hold the soles in position on said cover.

A block 69 is fixed to the front wall of spraying chamber 54d below the discharge opening 5i and fixed to said block and extending rearwardly therefrom into said chamber 54d is a pair of rearwardly diverging arms or rods Hi which form the support for the inner sole during the spraying operation. The latex is sprayed on to the channeled side of the inner sole by means of a spraying nozzle H which is arranged a suitable distance above the inner sole support 10. This nozzle has a connection 72 extending toward a latex container 14 and a compressed air connection 15 extending to a compressed air reservoir (see Fig. 24). This reservoir can be arranged at any suitable point with respect to the machine. The air connection 15 passes forwardly from said reservoir and then downwardly exteriorly of the operating side of the machine and is provided with a valve 11 normally closed and operable by a lever 18 into open position to allow the passage of air from the reservoir to the nozzle. This lever is pivotally mounted on the machine, as indicated at 79, and is so arranged that it can be operated by the left knee of the operator when the latter stands in operating position.

The latex container I4 is arranged rearwardly of the spraying chamber 55d and is supported on the cover 83 at a horizontal plane above the plane of nozzle 1!. Preferably this container is sealed on top and is provided at its lower end with an extension or well 78 which is of comparatively small area and is open on top and adapted to receive the upper end of the latex supply connection 72. A supply of latex is automatically maintained in said well at a predetermined level and the end of the connection 12 is disposed below said level.

The spraying nozzle ll consists of two sections, namely, the latex section Ma and the compressed air section lib. These sections are so arranged that they can be readily connected together or disassembled without disturbing the compressed air connections so that the latex section Ha can be easily removed for cleaning purposes.

This section Ha consists of a tubular elbow member Gil having a reduced end 853a connected to one end of pipe connection i2 and having its: opposite end 8% tapered exteriorly and formed with an enlarged bore 86 thereby forming therein an annular shoulder or seat S ta.

The compressed air section 'Hb consists of a lock 82 having a curved lower end and provided with a longitudinally disposed bore 83 closed near said lower end and open at the otherto receive the compressed pipe l5. This block is formed on one side at its lower end with a concave or semi-spherical recess 84 which communicates with the inner or closed end of bore 83 through an opening 85.

A washer or cylindrical member 86 is secured to the recessed side of block 82 by a screw 81 ccaxially with said recess. The diameter of this member 8'6 is larger than the diameter of said recess so that the latter is closed except at the lower portion which is left open by virtue of the fact that a portion of the peripheral face of said member 8% is cut away, as indicated at 86c. Immediately below this open portion of the recess the recessed face of the block is formed with a plurality of notches or grooves 88 which extend outwardly from said recess to the curved end of said block and form outlets therefor.

The diameter of bore ill of member 8i] is slightly larger than the diameter of member 86 so that the latter can be conveniently inserted therein when the sections Ma and "Nb are assembled together.

When thus assembled, a discharge passage is formed between the wall of bore 8! and the cutaway portion 880, through which latex is drawn from member 89. Member 86 is so positioned that the cut-away portion 86a is arranged adjacent to notches 88, thereby locating the open portion of the member 8% opposite to notches 88. Thus when the air is discharged from recess 84 through said notches 88 the latex is drawn from member 8K3 through the opening formed by cut-away portion a and is mixed with the air and then sprayed upon the channeled face of the inner sole held in position on supports it.

The screw 3'! extends through opening 85 and the lower end of bore 83-and this screw is of smaller diameter than either one of these so that the passage of air therethroug'h is not effected.

A pipe 5i having a valve 92 connects tank with a cylinder st in which operates a piston 95. This cylinder is located at the top of the forward end of the machine above plate 2! and piston 95 bears against the upper end of guide 41. Normally, spring t8 holds said guide in extended position shown in Figures 10, 15 and 16. When compressed air is admitted to cylinder 94, piston 95 is moved outwardly, thereby rocking said guide ll on its pivot lb so that the lower end of said guide moves inwardly, as shown in Figure 1 '7, thereby holding the strip ofcanvas between the inner sole and the lower end of said guide tau in readiness for the cutting operation.

A pedal 96 is used to operate cutting mechanism 49. This pedal is pivotally mounted on the door [5b, as indicated at 91, and has its rear end pivotally connected to the lower end of a link 98. The upper end of this link is pivotally connected to an extension 49b of the movable blade 49. A coiled spring 99 is anchored at one end to door I51) and at its other end is connected to a member [60 which is adjustably fixed to link 98. The tendency of the spring is to hold the blade inopen position and link 98 and the rear portion of pedal 96 in depressed position, as shown in Figure 11.

The forward end of pedal 96 is bent at right angle as indicated at 96a and extends in front of the operating side of the machine and below the knee-operated lever 18. A vertically slidable member I0! is mounted on the side of the machine and has its lower end bent laterally and forwardly to extend under the portion @811 of said pedal so that when the latter is operated, member H3! is caused to move downwardly. A coiled spring M2 is connected to the upper end of member HM and yieldably holds said member in normal or raised position.

The slack producing means All is operated by a piston I04 operating in a cylinder m5. This air cylinder is connected to tank 96] by a pipe 5%. A valve I61 controls the passage of air though said pipe I05.

It is desirable that the piston 95 be actuated before the piston 505 in order to obtain proper taut condition of the strip at the severing operation and before slack is produced in the strip. To this end, valves 92 and Ill! are arranged in spaced-apart rotation with each other to one side of member lill. A slidable horizontally disposed plunger l08 is interposed between member WI and valve Q2 and is adapted to be actuated when-member llll is depressed by the high portion Ifilb of said member so as to open valve 92. A similarly disposed plunger W9 is arranged between valve Hi1 and member I ill and is adapted to be actuated by the high portion mic of said member NH. The high portion iillc is spaced from plunger I09 so that the operation of plunger I08 and valve 92 takes place a predetermined length of time before'plunger I99 and valve l'll'l are actuated.

The pedal 96 is so arranged with respect to member Iill and link 98'that the actuation of plunger H18 and of the valve 92 and the corresponding piston 95 takes place before the severing operation of the strip. Thus the guide if is moved inwardly and holds the strip taut before the movable blade 49a is brought down while the operation of plunger 1% and valve E El! takes place after the severing operation. The valves 92 and I0! are of the bleeder type which permits the discharge of the air to atmosphere from the respective cylinders after each operation.

The slack producing means 4! which is mounted in the rear end of the base structure H is designed to produce slack in the canvas strip between the roll portion thereof and the canvas strip retaining member 45. Thus the canvas strip can be easily pulled through the machine when the forward end portion thereof is applied to the sole and the two moved forward together before the severing operation takes place.

This slack producing means includes a pair of rollers! l0 revolubly mounted in bearings Hi and a movable roller H2 which is journaled in bearings. H4 formed in'a movable carriage H5.

The bearings I I I are fixed on said rear end of structure II and the carriage H5 is slidably mounted in said structure II. The stationary rollers Hi7 are horizontally disposed and are spaced transversely from each other a sufficient distance to permit the movable roller I I2 to oper ate therebctween in a plane at right angles to the horizontal plane of the axis of rollers III].

The carriage H5 is fixed to the upper end of a piston rod H6 and this rod extends into a cylinder 35 and. is fixed at its lower end to piston IIl i disposed in said cylinder.

Normally, or with thecylinder I05 disconnected from the compressed air supply, the movable roller H2 occupies position below the horizontal plane of rollers H and the canvas strip, after the slack has been taken up, extends under and across said rollers Hi]. When the piston I 04 is actuated by the operation of valve I01, carriage II and roller H2 are carried upwardly. The extent of movement of roller H2 is a suitable vdistance past the rollers III]. During this movement said roller H2 engages that portion of the canvas strip extending between rollers III] and moves said portion upwardly past said roller as shown in Figure 7. As the canvas strip is held against retrograde movement by member 45, the upward movement of roller H2 causes the roll of canvas to unroll to provide the necessary slack in the canvas strip. When two rolls of canvas, as A and B, are used, two sets of rollers I I0 are used and the carriage H5 is also provided with two rollers I I 2.

On the downward movement of carriage H5 and rollers IIZ, a suitable length of canvas is released to produce the slack which can be readily taken up when the forward end portion of the canvas is applied to the sole at the front end of the machine.

In the operation of the machine, a plurality of soles is placed on table or shelf 56, the flange 56a forming a stop to prevent the soles from falling back of the machine. The operator stands in front of the machine adjacent to the forward end thereof. He takes one of the soles E and places it on member I0 with the channel F thereof presented toward the spray nozzle II and with the heel portion G presented forwardly and extending outwardly through opening 5|. He then presses with his knee lever I8, thereby releasing compressed air so that the adhesive or latex is sprayed through said nozzle on to the channeled side of the sole. The operator now moves the sprayed inner sole forwardly until the heel end G projects through opening 53 of plate 52. He then grips the projecting heel end G with his left hand and draws the sole forwardly through opening 5|. When the heel end H of the channel F is flush with the free end of the canvas strip C, he presses said end of the strip against the adhesive-coated face of the sole and grips both the sole and said strip end and pulls them forward, as shown in Figure 16, at the same time pressing the canvas portion against the channel face so as to cause it to adhere thereto.

When the toe portion of the sole E passes the upwardly presented edge of blade 49a, the operator presses the pedal 96. This actuates piston 95, causing the lower end of guide 41 to move rearwardly, thereby rendering and holding the canvas strip between the sole and the pin 41b taut. Immediately after this operation, the movable blade 49 is actuated to come against the stationary blade 49a thereby severing the strip portion attached to the sole from the base of the strip. The operator now removes the sole with the strip attached thereto and inserts a new sole into the machine on member "II! and repeats the operation.

When pulling on the forward end of this strip, the slack portion is taken up and it is not necessary to exert a great deal of pull. The slack producing mechanism 40 is automatically set in operation immediately after each severing operation so as to produce slack in the strip for the next sole.

The machinecan be used for applying canvas strips to outer soles as well as inner soles.

By using compressed air to apply the adhesive on to the channel face of the sole, the adhesive is forced under pressure against the leather. It is desirable to use about thirty pounds of air pressure to force the adhesive or latex in a fine spray against the sole. 'The adhesive used is preferably a liquid latex which is a commercial product and is composed of rubber and water with a very slight proportion of ammonia or other ingredients for the purpose of preserving it and preventing coagulation before being used.

By using air pressure the latex is forced into the fibers of the sole and particularly the channeled part thereof. Thus a thorough impregnation of the pores of the leather by the latex is provided, thereby obtaining a very efficient bond between the canvas and the leather. 1 It-is not necessary to make any exposure of the coated sole as there is no volatile solvent used in the liquid latex. After the canvas is cut out the canvas can be immediately pressed onto the sole and creased along the channeled portion thereof. Thus there is no waste of time between the spraying operation of the sole and the finishing operation. However, the sole can be sprayed and the canvas pressed thereto and creased after an interval of time or to suit the convenience of the operator, if so desired.

The application of the latex to the sole is important as it is well known that where rubber cement is used, two surfaces can not be united in a satisfactory manner without both surfaces receiving a coating of rubber cement. By spraying the sole with latex, both surfaces are rubber coated (the canvas has been pro-treated) and when pressed together adhere much more firmly than if the cement were applied to the canvas only and then the coated canvas applied to the dry surface of the sole.
